P38 EAS.... Help Needed

It wont pump up, it's at the very lowest it can get. It had been dropping when parked but pumping back up, but now it wont even pump up.
Where do I start?

check the compressor is working?
leak checks?
air bags?

Not sure if you are tech savvy, but found this

And you'll need to either build, buy or borrow a cable, but it's another tool in your kit !

If it's been losing height when parked it's got a leak, probably an air bag.
Leave the engine running for 15 mins with a door open to fully charge the air receiver.
Close the door and see if it lifts.
If it does squirt soapy water on the air bags and air lines and watch for bubbles.

Good luck.

Thanks for your replies so far. I took the rear wheel off because I thought I heard a leak, but now can't hear one. I can hear and feel the compressor working, but there are some weird clicking noises coming from the compressor area? They stopped and suddenly the suspension lifted?? Any ideas??

thats probably just the solenoids clicking to send the air to the right places, theres 7 on the valve block next to the compressor

may even be a dodgey o-ring in the valve block perhaps? leaking air past where it shouldn't

You have had a leak which has screwed compressor. Repair compressor then when you have air pressure again look for and fix leak.

As wammers says.Air pressure in the system is vital.The compressor is the source of pressure and must be good for the system to work.The compressor is easily overworked when compensating for a leak,and consequently worn out.Fix the leak and overhaul the compressor.

i've just having the same problem with mine, centre exhaust was blowing and been replaced. going to look at the air lines to the tank and rear air bags think they may have been melted as read somewhere on the forum, the front will still up and the back drops but won't pump up. been getting slower even after i replaced the pump
